toothed gear

An eccentric toothed gear is mounted on a hexagonal shaft.

The Cardassian-built airlock door resembled a large toothed gear.

A chain on a toothed gear cranked down one platform; the other inched down in time with it.

Aft, Wheeler and Murphy used toothed gears to point the nozzle.

The cycloidal gear profile is a form of toothed gear used in mechanical clocks.

The steering wheel rotates a shaft, at the other end of which is a circular toothed gear called a pinion.

A planetary reduction drive is a small-scale version using ball bearings in an epicyclic arrangement instead of toothed gears.

The cold-pressed parts, toothed gears and other components up to about two inches wide, were placed in a ceramic tube in the oven.

Gears work by transmitting power through rotational motion, and by realizing mathematical relationships between toothed gear wheels.

When two toothed gears mesh, an imaginary circle, the pitch circle, can be drawn around the centre of either gear through the point at which their teeth make contact.

No gearing for such a planetary display survives and all gears are accounted for, with the exception of one 63 toothed gear (r1) otherwise unaccounted for in fragment D.

Although some models were operated manually by foot pedals, some chain pumps were powered by a horizontal waterwheel which rotated large toothed gears and a horizontal axis beam.

Toothed gears having certain definite ratios are used to cause the winding drum for the cable and the cage for the spools to rotate at suitable relative speeds which do not vary.

For more forceful motion absorption and higher surface area, a paddle wheel or toothed gear is used, with a similarly ribbed or studded stationary interior wall to more forcefully grip the fluid/gel.

The automatic brake works by monitoring the speed using a centrifugal governor, connected by gears to a large toothed gear mounted on the pinion axle next to the wheel (i.e. it is not the pinion gear).

Lower power units are usually titled as "hammer drills," and typically have a "cam-action" or "percussion" hammering mechanism, in which two sets of toothed gears mechanically interact with each other to hammer while rotating the drill bit.

For example, one of the many devices described and illustrated in drawing is a large mechanical milling plant operated by the motive power of oxen, with an enormous rotating geared wheel engaging the toothed gears of eight different mills surrounding it.

Noise from the primitive toothed gear drivetrain (a characteristic common to contemporary MU cars on other railroads) could become quite loud at high speed which made the relative quiet of unpowered trailer cars (if utilized) attractive to some regular riders.

Vitruvius's account is particularly valuable in that it shows how the watermill came about, namely by the combination of the separate Greek inventions of the toothed gear and the water wheel into one effective mechanical system for harnessing water power.

A sensation of tapped power shakes the mill, and the horizontal shaft starts to rotate slowly, turning the creaking, grinding, wood toothed gears that convert the power from horizontal to vertical and send it to the floor below, and to the stones.

Some of the smallest machines for cotton covering have a large drum, which grips the wire and moves it through toothed gears; the wire passes through the centre of disks mounted above a long bed, and the disks carry each a number of bobbins varying from six to twelve or more in different machines.
